f ed new and useful Improvements in Safety (.farbureting Plants. of which the following isa specification.

The present invention relates to gas renerating plants for making power gas of that 'p type in which carbureting instrumentalities are provided to furnish and supply the carbu retcd air or gas for an explosive engine.

The purpose of the invention is to so assemble and combine the explosive engine and its carbureting and gas Supplying auxiliaries to safeguard the building in which the explosive engine or power device may be located from the danger incident to locating lllc supply of gasolbnbor other enriching fluid and the gasLforming devices within the building, it being a well established fact that where ga'solene in any quantity is stored or used in a building, the insurancerates are extremely high., and in many cases the under- 4writers refuse to insure buildings in which gasolene is kept.

Generally stated my invention contemplates the locating of the gasolene supply and the carburetor instrumentalities, at a distance from the explosive engine or power def vice, and wherethe same is used in a building for power purposes, outside of the building; and so connecting the engine and the carburetiug devices as that when the engine is started, it will draw from its outside source the or carbureted air the entire operation of delivering the gasolene to the carbureter and saturating the air therein, taking place outside of the structure,

Another feature of my invention relates to a novel form of pump for starting the carbugeting devices and feeding the gasolene thereto; which pump may be manually operated to supply a starting charge and thereafter will automatically supply the gasolene. By the use of this novel arrangement of pump, I am able to dispense with the obj eetional gravity feed from the main source of gasolene, which gravity feed is a menace to safety because of the danger of flooding and over-- flowing the carbureting devices in event of derangement of the parts, this supplying of gasolene from a lower level than the earbureting devices being looked upon with favor by the insurance underwrite s, for the reason that it is deemed safer than the ordinary gravity feed system.

In order that my invention may be under-` stood by those skilled in the art, I have illustrated in the drawings which' accompany and form a part of this specification, one embodiment of my invention and in said drawings: Figure 1 is a side elevation of an apparatus constructed in accordance with tlns invention, the same being shown in connection with a gas engine located `within a building; and Fig. 2 is an enlarged detail ,View of the earbureting-apparatus, certain parts lthereof being shown in section.

Referring to the drawins by numerals, like numbers indicating like parts in the several views, 2 (Fig. 1) represents an eX- plosive engine or power device of any suitable ty ie, located within a building 3 in any desirable position. From the engine 2 a gas suction pipe 4 leads to a carbureting device 5, which 1s located outside of .the building in any suitable place, and it may, if desired, be placed in a suitable vault below the surface of the ground, as shown. The said carbureter 5 is connected by a suitable feed pipe 5a with a gasolene supply tank 6, located at any suitable distance therefrom, said tank having the usual filling and ven pipe 6zal as shown. The said carburetor 5 may be of any approved float controlled type, and as its inner arrangement is of no consequence, so far as the present invention is'concerned, I do not illustrate or describe the interior construction thereof. The carbureter' 5, as stated, is connected with the I storage tank 6, which is preferably at a lower level than the carbureter 5, by means of the gasolene supply pipe 5 and in said pipe between the carbureter 5 and the storage 6, is a pump 8 comprising a cylinder and reci rocating piston, suitable check valves 9 o ordinary construction to permit inflow and outflow past the pump being located on either side of the pump 8, as shown. The piston of the pumpS is connected with a lever 10 pivotally mounted at one end on the casing of the earbureter 5, and having a connection 1 1 with the air valve 12 of the vacuum chamber of the carbureter. The said lever 10 is provided with a handle 13 by means of which the pump 8 may be manually operated, and it will be seen that as the pum 8 is operated, the air valve 12 of the car ureter will be lifted, and a starting charge supplied by 1s provided with the usual 'needle valve (not shown), through which the gasolene is drawn into the vacuum chamberand mixed with the air. The small supply tank 14 is preferably provided With an overow return pipe 16, which leads therefrom to the main storage tank 6, so that the small supply tank 14 Wlll only contain a sufficient amount of gasolene to keep the carbureter supplied; 4It Will be seen that by means ofthis combined manual and automatic pump, aI sup ly of gasolene may at first be manually andJ then automatically drawn from a lower level and fed to the carburetor in proper proportion to furnish a constant supply, and as the stroke of the`pump 'Will vary directly with the pull on the air valve, the gasolene-supply will vary according to the work and the needs of the engine.

It will be understood, of course, that many variations in mechanical construction may be made without departin from the spirit of my invention, and as I eem all such inechanical expediente to be within the purview thereof, I do not limit myself to any of the details herein shown and described, ex-

cept so far as I am limited bythe priorart to which the invention belongs.

While I have described the present invention in connection with gaslolene as the fluid` esame fuel, it will be understood that any other suitable fluid, as, for example, alcohol, may be used in vconnection with my apparatus to enrich air and form the eX lesive charge; and I do not, therefore, wish to be understood' as limiting the use of my invention to" y any particular fuel. v

Having thus described my invention what I claim as new and desire to secure byy Let- I50 1. The combination with a-carbureter, of l ters Patent is f an air intake valve therefor, a source of fluid supply, ay feed connection between said carbureter and said suppl and a ump in said feed connection controlled by t e a1r intake valve of said carbureter.

2. The combination With a 'carburet'en of an air intake valve, a source of fluid supply,

a feed pipe connecting said carburetorr and said supply, a vpump in said feed pipe, and

connections between said pump and the. airvalve of the carburetor foractuat'mg the s 'aid pump. A

3. The combination With a carbureter, of suction means therefor, an air intake valve, a source of fluid supplyfor saidcarbureter, a feed pipe connecting'` said carbureter with' said source of supply, a manually operable pump in said feed pipe and connections between said pump and the air valve of said carbureter to automatically operate 'said pump Whenthe suction means' is running.
